This post is written by Thomas Moore, Solutions Architect, Serverless. When using AWS Lambda to build serverless applications, customers often need to retrieve parameters from an external source at runtime. This allows you to share parameter values across multiple functions or microservices, providing a single source of truth for updates. A common example is retrieving […]

This blog post provides a step-by-step guide on securely invoking a cross-account Step Functions workflow from a central account using API Gateway as front end. This pattern can be extended to scale workflow executions across different Regions and accounts.

This blog post describes how to compose a nested Step Functions workflow, which asynchronously manages a custom service using the polling mechanism.

This blog post demonstrates how to implement a serverless image cataloging pipeline using Step Functions Workflow Studio. By orchestrating AWS API actions and flow states via drag and drop, you can process user-generated images. This example checks images for appropriateness and generates tags based on their content without custom application code.

This post is written by Sam Dengler, Principal Specialist Solutions Architect, and Dhiraj Mahapatro, Senior Specialist Solutions Architect. AWS Step Functions now supports over 200 AWS Service integrations via AWS SDK Integration. Developers want to build and test control flow logic for workflows using branching logic, error handling, and retries. This allows for precise workflow execution with deterministic […]

This post is written by Anitha Deenadayalan, Developer Specialist SA, DevAx Modern applications use microservices as an architectural and organizational approach to software development, where the application comprises small independent services that communicate over well-defined APIs. When multiple microservices collaborate to handle requests, one or more services may become unavailable or exhibit a high latency. […]

Welcome to the 16th edition of the AWS Serverless ICYMI (in case you missed it) quarterly recap. Every quarter, we share all of the most recent product launches, feature enhancements, blog posts, webinars, Twitch live streams, and other interesting things that you might have missed! In case you missed our last ICYMI, check out what […]

Amazon Athena console now provides an integration with AWS Step Functions’ workflows. You can use the provided patterns to create and visualize Step Functions’ workflows directly from the Amazon Athena console. Step Functions’ workflows that use Athena’s optimized API integration appear in the Athena console. To learn more about Amazon Athena, read the user guide.

This post shows how to create a Step Functions workflow for Forecast using AWS SDK service integrations, which allows you to use over 200 with AWS API actions. It shows two patterns for handling asynchronous tasks. The first pattern queries the describe-* API repeatedly and the second pattern uses the “Retry” option. This simplifies the development of workflows because in many cases they can replace Lambda functions.

This blog post shows how to use Step Functions’ features and integrations to orchestrate a batch processing solution. You use two Steps Functions workflows to implement batch processing, with one workflow splitting the original file and a second workflow processing each chunk file.
